Subject: General question about caching
Date: Fri, 02 Apr 2004 11:20:31 -0500 [thread overview]
Message-ID: <406D92CF.8040302@gcctech.com> (raw)
I have a tight footprint, and no swapping (in fact no disks). I notice
that /proc/meminfo reports:
total: used: free: shared: buffers: cached:
Mem: 31686656 30740480 946176 0 4591616 12210176
Swap: 0 0 0
MemTotal: 30944 kB
MemFree: 924 kB
MemShared: 0 kB
Buffers: 4484 kB
Cached: 11924 kB
SwapCached: 0 kB
Active: 22196 kB
Inactive: 5416 kB
HighTotal: 0 kB
HighFree: 0 kB
LowTotal: 30944 kB
LowFree: 924 kB
SwapTotal: 0 kB
SwapFree: 0 kB
I only have rom and ram-based file systems, so I believe that disk
caching could and maybe should be reduced to use less space. Can I
control this? How? I notice that most of the cache_init routines
running in init/main.c use mempages as the arg. What would be the
ramifications of simply reporting less memory to those functions?
Downside? Danger?
Your input is appreciated!
